If we have intercourse every second day, will I eventually get pregnant?

You might want to go to the doc and just get checked over. A very long cycle can make it a little harder and you may have some hormonal changes. They could check everything and give you some suggestions. Every second day is a good frequency to catch ovulation, but remember that a healthy person has about a 20% chance of getting pregnant each month. There are lots of reasons why you might not conceive immediately, some perfectly benign and some perhaps that could use attention. If you are worried it never hurts to get a check up.
